Abstract
Vermicompost was enriched with Azotobacter chroococcum, Pseudomonas spp. P-36 ,
Pseudomonas maltophilia PM4 and AM fungi (Glomus mossae). The microbially
enriched vermicompost was analysed for organic C, total N, total P, ammonical N and
nitrate N and microbial population. Organic C was decreased in the microbially enriched
vermicompost after 30 days due to microbial activity. Total N and total P content
increased due to inoculation of Azotobacter chroococcum, Pseudomonas spp., and AM
fungi (Glomus mossae). Microbially enriched vermicompost showed higher count of
Azotobacter chroococcum, Pseudomonas spp., Pseudomonas maltophilia upto 30 days.
Seedling of Aonla and Bael grown in microbially enriched vermicompost for 60 days
showed increase in shoot and root length and plant dry weight. Seedling grown in AM
fungi (Glomus mossae) enriched vermicompost had higher infection of AM fungi
(Glomus mossae) as compared to control or vermicompost enriched with Azotobacter
chroococcum, Pseudomonas spp., Pseudomonas maltophilia
